title: Use of the cochlear implant by the prelingually deaf.
abstract: Introducing sound to the prelingually deaf adult presents a special challenge to those concerned with the rehabilitation of the deaf utilizing the cochlear implant. Twelve subjects with an early loss have undergone implant surgery and have been fitted with external stimulator devices. Eight of the 12 subjects are considered successful users. Electrical thresholds are comparable to those for the postlingually deaf. However, the prelingual subjects initially have a reduced tolerance for sound and often react differently than the postlinguals. The prelinguals do not always respond to the sensation as sound, but rather as a feeling or vibration in the head. However, like the postlinguals, the prelingually deaf report being able to respond to attention-getting sounds, such as horn-honks and their names being called; and voice quality changes have been noted. These subjects find music particularly enjoyable through the implant. In addition, they have reported feeling more independent, more social, and even less lonely.
